Advancements, Trends and Future Prospects of Lower Limb Prosthesis

Amputees with lower limb loss need special care during daily life activities to make the movement natural as before amputation. No such work exists covering main aspects from causes of amputation psycho-social impact amputees after using prosthetic device. This review presents for prosthesis; study amputation, design & development, control strategies machine learning algorithms, users, and trends in patents. Research articles, papers, magazines, letters, reports, surveys, patents, etc. have been used sources this review. Traumatic injuries different diseases found common Design development section illustrates mechanisms, categories passive, active, semi-active prostheses, an overview a subset commercially available devices, 3D printing accessories. The provides information about techniques, sensors used, their key outcomes. Quality life, phantom pain, users summarized countries that are believed attract interest readers. We also developed open-source database “FAKH-50” patents emphasize advancements prostheses 1970 2020. Overall trend analysis determined is descending order knee (48%) > ankle (28%) foot (22%) hip (2%) current version our database. forthcoming highlights challenges prospects domain. A mutual observation demands bio-compatible, lightweight, economic prosthesis track normal human gait by eliminating pain. will empower live quality society. may be beneficial researchers, technicians, clinicians, amputees.
